Fig. 6: Evolution of the ANAIS–112 sensitivity to the DAMA/LIBRA signal over time and sensitivity obtained in this work.

Dark blue line: the ANAIS–112 sensitivity to the DAMA/LIBRA signal is represented in σ confidence level (C.L.) units as a function of real time in the [1-6] keV (a) and [2-6] keV (b) energy regions. The black dot is the sensitivity measured experimentally in this work. The cyan bands represent the 68% C.L. DAMA/LIBRA uncertainty. Red dashed and red solid lines correspond to reference values of 3σ and 5σ, respectively.
